Days Between Dates
Precise date difference calculator. Count total days, weekdays, weekends, weeks and hours between any two dates — with an optional include-end-date toggle.
How Date Calculator works
Choose a start date and end date using the native date pickers.
Flip 'Include end date' on if you're counting nights, deadlines, or contract periods.
Total days, weeks, hours, weekday/weekend split, and a calendar-aware years/months/days breakdown — all update live.
Frequently asked
What's the difference between including and excluding the end date?+
Excluding the end date gives the raw span (e.g. Jan 1 → Jan 3 = 2 days). Including it counts both endpoints (e.g. Jan 1 → Jan 3 = 3 days) — useful for hotel nights, project deadlines, or contract lengths.
Does this handle time zones?+
Dates are treated as UTC midnight, so daylight-saving transitions and time-zone differences never skew the count.
How is the weekday count calculated?+
We iterate day-by-day between your dates and count Mon–Fri as weekdays and Sat–Sun as weekends. Public holidays are not deducted — this is a raw calendar count.
What if the end is before the start?+
Negative direction is auto-corrected — we always show the absolute count.
